I am trying to compile a ruby-c extension with ruby1.9.1 (binaries
downloaded from on windows using VS 2008. when I run
ruby extconf.rb I get an error as below.

c:/ruby191/lib/ruby/1.9.1/mkmf.rb:363:in `try_do': The complier failed
to genera
te an executable file. (RuntimeError)
You have to install development tools first.

        from extconf.rb:26:in `<main>'

What development tools is it expecting? how will I be able to install
the same?

Any help is highly appreciated.

The binary downloaded from ruby-lang is compiled using VS 6.0.
And it is not compatible with VS 2008.
You should install VS 6.0.
